Cisco Anyconnect Vpn Installer Package Editor Sims
I was visiting China recently (my first time there). I thought bypassing The Great Firewall was going to be as simple as an 'ssh -D' SOCKS setup, or a 'ssh -w' tunnel. Oh boy, I was wrong.
If you try this, or even a basic OpenVPN setup, you will quickly find out your VPN works fine for about 5 minutes, but then latency increases to 5sec, 10sec, 30sec(!), and then everything times out. After some research I read online the government does deep packet analysis and uses machine learning to find heuristics to guess which TCP connection or UDP stream is likely being used as a VPN.

Encryption is not enough. You need to disguise your VPN traffic to make it look like standard HTTPS sessions (since they don't block HTTPS).
For example in a traditional HTTPS session, if the client browser downloads, say, a 500kB image over HTTPS, it will send periodical empty TCP ACK packets as it receives the data. But when using a VPN that encrypts data at the IP layer, these empty ACK packets will be encrypted, so The Great Firewall will see the client sending small ~80-120 bytes encrypted packets, and will count this as one more sign that this might be a VPN. That's why people in China have to use VPN tools that most westerners have never heard of: obfsproxy, ShadowVPN, SoftEther, gohop, etc. All these tools try to obfuscate and hide VPNs. I have a lot of respect for all these Chinese hackers like clowwindy who try to escape censorship, as it takes more technical prowess than you think to design a VPN that works in China. I am in Iran, you cannot believe it, same here, They use deep packet inspection too, they will shut every package down.

Every open vpn, cisco vpn, etc connection will lose connection every 2-3 min. Connection to outside web is almost impossible. I have noticed they have multiple situation, for example when everything's quiet internet is not so bad (despite the fact bandwidth is extremely low for huge amount of people), but when some news came out about government corruption, guess what? Some vpn does not work.
In 2009 green movement they closed every https connection.(maybe that was red alert situation) p.s: p.s.: I use vps from netherlands for bypassing firewall. But It takes huge amount of time and a little money.but the point is 99.999% people don't have this option (I use shadowsocks, sometimes another tunnels) so they use internet the way is or some software like freegate and other but with extremely low speed unbearable lag. P.s.: pptp, l2ps and others are closed right now. Even president rohani couldn't manage the situation.
I have heard he did want to do something but supreme leader and his people stopped him. A few years ago I had a friend visiting Iran who wanted unrestricted access to sites. I didn't have any personal Linux servers on the internet at the time, but I did have a Windows one with Remote Desktop licenses. It turned out that RDP actually worked pretty well. I did hesitate to post this in case it's seen by the wrong people(!), though given it's a while since it was necessary to use, it may be blocked by now anyway.
I wonder if it was available because it was relatively little known and, if so, what other little known protocols might be available. At first China also used Cisco's stuff, but soon they could't keep up with the requirements of the Chinese govt.
After that a man usually criticized to be 'the father of GFW', FANG Binxing, came up and built more powerful censorship hardware and software for the govt at Beihang U. It is said that they now use supercomputers to parse, analyse and block (and even inject, remember GitHub?) all packages going through the Chinese network boundary. Oh I just gave away so much secret. I'm so doomed. Everything above are just made up stories. Don't believe me. Don't track me down.
